TELETYPE MODEL 15 PAGE PRINTER

TELETYPE MODEL 15 PAGE PRINTER

The Teletype Corp Model 15 is a rugged machine, capable of continuous operation. It was the machine often seen clattering away behind newscasters on TV years ago.

(need more poop here)....

The M15 uses a lot of technology from the M14 line -- I see the same keyboard, keyboard-shaft/encoding-switches, motor, and selector/rangefinder in my M14-KTR. Relatives include the Model 19 Set, which uses a modified M15 with integral paper-tape perforator and character counter. While the M15 uses the 5-level baudot code, Model 20 machines (based on the M15) use the 6-level teletypesetting (TTS) code.

The Teletype Corp Model 15-KSR... (need more poop here)... The military Model TG-7-A is slightly modified for field use. The printing unit is packed in chests CH-50-A and CH-62-A. One chest serves as an operation table for the printer, and the other chest is used as a seat. The Model TG-7-B is similar, but lacks a relay block, polar-neutral key, motor control relay, and a terminal block. The TG-7-B uses chests CH-62-B (or F), and CH-50-B (or F).

This is my M15-KSR -- works great! More pics here.

This M15-KSR is missing the glass from the case window.

The M15 had an optional table or two.

Western-Union chose monkey-vomit green for this M15-KSR.

This Western-Union M15-KSR is in the wide "mailbox" or "post-office" floor-standing case. Jim Haynes has a 50-baud Telex service M15 in this kind of cabinet.

The military TG-7-B is an M15 that packs into shipping crates.

The typing unit on this TG-7-B is in the other crate. Note the black-and-white stripes on the motor flywheel, indicating that this is a governed DC motor.
